Abstract

PURPOSE:To obtain a precise converter which performs a quick response using a simple circuit by a method wherein in the rectified output of the main transformer is used as a power source, and an oscillation device is consisted of a multivibrator which is driven by the rise or fall of AC output of the main transformer. CONSTITUTION:A square wave in proportion to secondary voltage can be outputted by the FF12 which will be set or reset by the output phi1 and phi2 of the main transformer 2 using the secondary side output voltage as source voltage. In other words, the setting and resetting of input of the FET12 is triggered by each positive voltage section of the output phi1 and phi2, the continuity angle of which is controlled by the main transformer 2, and outputs Q and Q' are obtained. On the other hand, the outputs phi1 and phi2 are rectified by a rectifying and smoothing circuit 3, and as this output voltage is used as the power source voltage VDD and VSS of the FET, the output voltage Q and Q' is modulated by the secondary side output voltage. Accordingly, a precise insulated type converter, which response quickly using a simple circuit, can be obtained.
